(original) (raw)

Thanks - It helps a lot.

I was managed to locate the java file that cause the problem and by elimination the line.

The exception was caused by missing dependency.

The line is:

        PostProcessor.registerRequiredReferences(ResultsSaver.getResultsSaverServiceImpl(),
                                                 ScanStatisticsCollectorHelper.getStatisticsCollectorServiceImpl(),
                                                 SynchWithScanHelper.getProcessingControlServiceImpl());

The problem:

ScanStatisticsCollectorHelper implements DefectsProcessor

I'm compiling unit (Jar) C.
ScanStatisticsCollectorHelper is compiled in unit B
DefectsProcessor is in unit A.

When compiling C, A is not in classpath. And this what caused the exception. After adding A compilation succeeded.


Also we have exception from the exact same reason:

    \[javac\]     at com.sun.tools.javac.code.Types.rank(Types.java:3043)
    \[javac\]     at com.sun.tools.javac.code.Types.rank(Types.java:3015)
    \[javac\]     at com.sun.tools.javac.code.Types.rank(Types.java:3019)
    \[javac\]     at com.sun.tools.javac.code.Types.rank(Types.java:3019)
    \[javac\]     at com.sun.tools.javac.code.Symbol$TypeSymbol.precedes(Symbol.java:591)


We have many issues like this in JDK 8\. C->B->A. In JDK 7 we just add B to C classpath and it was compiled successfully. In JDK 8 we have 3 different results:

1\. A message  that A cant be found
2\. Exception: at com.sun.tools.javac.code.Types.rank(Types.java:3043)
3\. Exception: at com.sun.tools.javac.comp.Flow$FlowAnalyzer.visitApply(Flow.java:1196)

Thank you for your help.

Add

\-XDverboseCompilePolicy

That should print detailed info about what the compiler is doing (i.e. which file it's compiling before the crash).

Because I'm compiling large number of files, I have no way to know which one causes the problem.
I added -verbose But it didn't help match (maybe if I send the output it to you ?)
Is there any thing I can do to get more information ?

Thanks
Boaz
